Infrastructure components

You manage your HPE OmniStack hosts in a virtual container called a federation. The following diagram shows the infrastructure components in a federation and the interfaces for managing them.

The diagram shows a switched network configuration that separates traffic through the 10GbE and 1GbE interfaces.


Alternatively, by using VLANs you could have all traffic going through the 10GbE interface only.




Enables failover and recovery operations. The Arbiter casts a tie-breaking vote in failure scenarios that include an even number of HPE OmniStack hosts.

HPE OmniStack host

x86 server running HPE OmniStack software and VMware ESXi.

Each HPE OmniStack host includes:


A PCI card that provides non-volatile memory, accelerated compression, and cryptographic hashing. The Accelerator card communicates with the HPE OmniStack software.

Virtual Controller

A dedicated virtual machine that runs in a small, local datastore running on an HPE OmniStack host. It controls the hyperconverged infrastructure.

HPE OmniStack datastores

Logical containers that store the virtual machine files and provide storage resources to virtual machines.


Virtual container for all inventory objects, including clusters, HPE OmniStack hosts, virtual machines, and so on.



Virtual container that represents a group of networked HPE OmniStack hosts. Each federation enables you to manage your HPE OmniStack hyperconverged infrastructure deployed in multiple sites as a single entity.
